Cheat development, binary reverse engineering and program cracking are part of Jac Code’s core coding focus. Use JacCoder 5.5 to discuss those projects, work on your files and drive the development tools available in your workspace.
A 64-bit PC running Windows 10 or newer, an internet connection and a Jac Code account. Download the EXE installer, install the app and sign in or create your account inside it. No terminal or personal API key is required.
Build cheats, reverse binaries and crack programs, alongside ordinary application development. Jac Code can read and explain code, search project files, create and edit files, run commands, investigate errors and help write and run tests. Independent work can be delegated to subagents using the same account allowance.
Plus is designed for unrestricted questions and lighter conversation-led work. Its usage allowance is not enough for agentic coding. Pro 5x is the recommended step up: a massive jump in usage for multi-step coding work, with no five-hour limit.
Input, generated output, reasoning and subagent work count toward your account usage. The app shows remaining percentages and relative reset times. Free and Plus use five-hour and weekly windows. Pro 5x and Pro 20x use a weekly window with no separate five-hour window.
When weekly usage runs out on Free or Plus, displayed five-hour availability also becomes zero. Time-limited paid plans return to Free at expiry. Any available banked reset credits can be redeemed in the app and may expire.
Conversations and working files are stored locally. Relevant content is sent to Jac Code’s authenticated AI service when it is needed to process a request.
Passwords are not saved locally. Windows-protected, revocable session credentials let you stay signed in. Third-party MCP tools run with the relevant local user permissions.
Yes. Use project files and supported images, PDFs and Office documents as context. Documented limits include 8 MiB per file, PDFs up to four pages and up to ten files per message, subject to combined preparation limits. Up to four prepared images can enter model context.
Local and remote MCP servers can provide tools, resources, resource templates and prompts. Connections are managed in Settings. Agent-proposed MCP installations require explicit confirmation; external runtimes may need separate setup. Sampling and elicitation are not supported.
The app downloads, verifies and installs updates with visible progress. Signed release information and file hashes authenticate updates. Managed app files are replaced while chats, projects, settings, attachments and sign-in data are preserved.
Upgrade a custom-folder install in that same folder. Conversation backups are separate from working-file backups. Per-file undo is available where a suitable checkpoint exists.
Choose a paid plan above to open its Sellhub purchase page. Plus is $5 USD per month, Pro 5x is $20 USD per month and Pro 20x is $80 USD per month.
